[0039] Please refer to Figures 1 to 5 , this embodiment provides a device 3 for a spray branch pipe to pass through a beam. The device 3 for a spray branch pipe to pass through a beam is used for the spray branch pipe 2 in a fire protection system to pass through a beam for pipe laying, that is, during the construction of the spray branch pipe 2 in the fire protection system, the spray branch pipe 2 can pass through the device, so that the spray branch pipe 2 penetrates through the structural beam 1. As Figure 1 shown, the device 3 for a spray branch pipe to pass through a beam can be embedded in the structural beam 1 during building construction, and then during the construction of the spray branch pipe 2, the spray branch pipe 2 is passed through the device 3 for a spray branch pipe to pass through a beam, thereby realizing installation without punching holes and improving construction efficiency.

[0040] As Figure 2 shown, in this embodiment, the device 3 for a spray branch pipe to pass through a beam includes: an embedded pipe 31 and a support lining 32. Among them, the embedded pipe 31 is embedded in the structural beam 1 along the width direction of the structural beam 1 of the building, and the embedded pipe 31 is used for the spray branch pipe 2 to penetrate through the structural beam 1, thereby realizing installation without punching holes. The embedded pipe 31 is any one of a PVC pipe, a PP pipe, and a galvanized pipe.

[0041] The support lining 32 is fixedly arranged inside the embedded pipe 31. The support lining 32 is a ring-shaped structure with a certain length. The support lining 32 is used to support the spray branch pipe 2. A channel 322 for the spray branch pipe 2 to pass through is arranged in the middle of the support lining 32; so that the weight of the spray branch pipe 2 can be transmitted to the embedded pipe 31 and the structural beam 1 through the support lining 32. The support lining 32 is fixed in the embedded pipe 31 by bolts or structural adhesive.

[0042] As Figure 3 shown, at least one end of the channel 322 is provided with an inwardly concave conical guiding surface 321, and the channel 322 is located at the central position of the guiding surface 321. In order to facilitate the insertion of the spray branch pipe into the channel, the included angle between the guiding surface 321 and the horizontal direction is 45 degrees - 60 degrees.

[0043] The length of the embedded pipe 31 should be greater than or equal to the width of the structural beam 1, so that both ends of the embedded pipe 31 are exposed on the surface of the structural beam 1. During construction, the length of the embedded pipe 31 can be cut according to actual needs. To prevent concrete from entering the interior of the embedded pipe and blocking the channel 322 during the construction of the structural beam 1, detachable sealing caps are provided at both ends of the embedded pipe 31. During construction, first seal the sealing caps at both ends of the embedded pipe 31, then embed the embedded pipe 31 in the structural beam 1. Then, when laying the spray branch pipe 2, remove the sealing caps at both ends, so that the spray branch pipe 2 penetrates into the channel 322 in the support lining 32 and exits from the other end of the embedded pipe 31. In this embodiment, one end of the spray branch pipe 2 is connected to the spray main pipe, and a fire sprinkler head is provided at the other end of the spray branch pipe 2.

[0044] In the above embodiment, the support lining 32 may be provided with the above-mentioned guiding surface 321 only at one end. Therefore, during construction, the spray branch pipe 2 is inserted into the embedded pipe 31 and the support lining 32 from the end provided with the guiding surface 321. In some other embodiments, the guiding surfaces 321 are provided at both ends of the support lining 32. Therefore, during construction, the spray branch pipe 2 can be inserted from either end.

[0045] In some embodiments, the support lining 32 includes an elastic support portion 324 provided on the outer layer of the annular structure and a polytetrafluoroethylene layer 323 provided inside the elastic support portion 324. The outer side of the elastic support portion 324 abuts against the inner wall of the embedded pipe 31, and the inner side of the polytetrafluoroethylene layer 323 abuts against the outer wall of the spray branch pipe 2. The elastic support portion 324 is made of rubber or thermoplastic elastomer; the thermoplastic elastomer includes any one of styrene-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, polyolefin-based thermoplastic elastomers, and polyamide-based thermoplastic elastomers.

[0046] To effectively support the weight of the spray branch pipe 2, the inner diameter of the channel 322 in the above-mentioned support lining 32 is basically equal to the outer diameter of the spray branch pipe 2, or the inner diameter of the channel 322 is slightly larger than the outer diameter of the spray branch pipe 2. Therefore, to reduce the resistance when the spray branch pipe 2 passes through the channel 322, in this embodiment, a polytetrafluoroethylene layer 323 is provided on the inner side of the channel 322. The polytetrafluoroethylene layer 323 has good self-lubricity and can effectively reduce the resistance when the spray branch pipe 2 penetrates.

[0047] In one embodiment, the above-mentioned sprinkler branch pipe beam-passing device 3 further includes a heat-insulating filler. The heat-insulating filler is made of a heat-insulating material and is used to fill the space between the sprinkler branch pipe 2 and the embedded pipe 31. The heat-insulating material includes any one of fiberglass, polyurethane foam material, and EPE pearl cotton. During use, after the sprinkler branch pipe 2 passes through the embedded pipe 31 and its position is fixed, the above-mentioned heat-insulating filler is filled into the space between the sprinkler branch pipe 2 and the embedded pipe 31. The above-mentioned heat-insulating filler can play a role in heat insulation and heat preservation.

[0048] In the above embodiment, the sprinkler branch pipe beam-passing device 3 includes an embedded pipe 31 and a support lining 32. Among them, the embedded pipe 31 is used to be embedded in the structural beam 1 to achieve beam-passing without drilling holes, improving the efficiency of pipe-laying construction. The support lining 32 is arranged in the embedded pipe 31 and is used to support the sprinkler branch pipe 2. Therefore, the weight of the sprinkler branch pipe 2 can be transmitted to the structural beam 1, reducing the number of suspender rods of the sprinkler branch pipe and improving the construction efficiency. At the same time, it can also save equipment costs. And at the end of the support lining 32 (i.e., the end of the channel 322), there is an inwardly concave conical guiding surface 321, which is convenient for the sprinkler branch pipe to align with the channel 322 during construction, improving the construction efficiency.

[0049] In another embodiment, a sprinkler device is provided. The sprinkler device is arranged in a building and includes a sprinkler branch pipe 2 in a fire protection system and a beam-passing device that is embedded in the structural beam 1 of the building and enables the sprinkler branch pipe 2 to pass through the structural beam 1. Among them, one end of the sprinkler branch pipe 2 is connected to the main sprinkler pipeline, and the other end of the sprinkler branch pipe 2 is connected with a fire sprinkler head; the beam-passing device is the sprinkler branch pipe beam-passing device 3 described in any one of the above embodiments.

[0050] Finally, it should be noted that although the above embodiments have been described in the text of the specification and the drawings of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solution obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of the present application and using the content recorded in the text of the specification and the drawings of the present application, as well as any technical solution directly or indirectly implementing the above embodiments in other related technical fields, is included in the patent protection scope of the present application.
